Recurrent Atrial Fibrillation Disrupted His Retirement
John (pseudonym) is an Australian retiree who had previously enjoyed an active lifestyle.
That changed when he began experiencing episodes of atrial fibrillation (AFib).
Within several months, he experienced two significant episodes.
One occurred following a meal with friends. According to the hospital’s account, alcohol was associated with the episode and his heart rate suddenly increased to approximately 180–200 beats per minute.
Another episode occurred while he was cycling outdoors.
This time, the abnormal heart rhythm reportedly continued for approximately 10 hours.
John sought medical attention in Australia and was diagnosed with paroxysmal atrial fibrillation.
Both episodes required medication to restore his heart rhythm, and he subsequently began taking anticoagulant medication.
However, the possibility of recurrent episodes and the prospect of continued medication led him to explore additional treatment options.

Travelling From Australia to Shenzhen for AFib Treatment
After researching his options, John decided to travel from Australia to Shenzhen, China.
He sought treatment at the Department of Cardiac Arrhythmia at The University of Hong Kong-Shenzhen Hospital, where he was evaluated by Professor Li Haiying and the cardiac electrophysiology team.
Following a detailed assessment, the team recommended radiofrequency catheter ablation for atrial fibrillation.
The decision to perform an ablation was based on John’s individual condition and specialist evaluation.
⸻
What Is Radiofrequency Catheter Ablation for Atrial Fibrillation?
Atrial fibrillation is an abnormal heart rhythm caused by disorganized electrical activity in the heart.
For selected patients, catheter ablation may be considered as part of AFib treatment.
During the procedure, thin catheters are introduced through blood vessels and guided into the heart.
Specialized mapping technology can be used to identify areas associated with abnormal electrical activity. Radiofrequency energy is then applied to targeted cardiac tissue as part of an attempt to prevent abnormal electrical signals from triggering or maintaining atrial fibrillation.
Catheter ablation is a minimally invasive procedure because it does not require conventional open-heart surgery.
However, not every patient with atrial fibrillation is an appropriate candidate for catheter ablation.
The decision depends on factors including the type of AFib, symptoms, previous treatment, underlying heart disease, stroke risk and the patient’s overall medical condition.

A Two-Hour Catheter Ablation Procedure in Shenzhen
Before the procedure, the medical team discussed the treatment and process with John.
According to the hospital’s report, the procedure was performed under local anesthesia with the assistance of a 3D cardiac mapping system.
The ablation took approximately two hours.
John remained conscious during the procedure and the hospital reported that he experienced no significant discomfort.
By the following day, he was able to get out of bed and independently manage his daily activities.
⸻
Follow-Up After the Procedure
The hospital continued to follow John’s condition after treatment.
According to the published case, his heart rhythm remained stable during approximately two months of follow-up, with no further reported episodes of atrial fibrillation during that period.
Following evaluation by his treating medical team, the hospital reported that his antiarrhythmic and anticoagulant medications were discontinued.
John subsequently returned to activities he enjoyed, including cycling and travelling.
It is important to emphasize that this was one individual patient’s reported outcome.
Whether medication — particularly anticoagulation — can be reduced or discontinued after AFib ablation depends on an individual’s circumstances and must be determined by the treating cardiologist.
Patients should never stop anticoagulant or heart-rhythm medication without medical advice.
⸻
Why Might Catheter Ablation Be Considered for AFib?
According to the treating team featured in the original hospital report, catheter ablation can be an important treatment option for selected patients with symptomatic paroxysmal atrial fibrillation.
It may be considered in circumstances such as persistent symptoms, inadequate control with medication, medication intolerance or other clinical considerations.
However, treatment decisions are individualized.
Some patients may be managed primarily with medication, while others may be considered for catheter ablation or other interventions.
A cardiologist or cardiac electrophysiologist should assess the appropriate approach for each patient.
⸻
What Can International Patients Learn From This Case?
1. Treatment abroad is not always about receiving a diagnosis
John had already been diagnosed with atrial fibrillation in Australia.
His reason for seeking treatment in China was therefore different from someone travelling abroad simply to obtain a diagnosis.
He was looking for another approach to managing a condition that was already affecting his quality of life.
For international patients, this distinction is important.
Medical travel may involve seeking:
Another specialist opinion
A particular procedure
A specialist team with relevant experience
Different treatment options
More convenient access to treatment
The appropriate reason will vary considerably from patient to patient.
2. Look for the relevant specialty, not simply a famous hospital
For atrial fibrillation, the experience of the cardiac electrophysiology or arrhythmia team can be particularly relevant.
International patients researching treatment should consider asking questions such as:
Does the hospital have a dedicated arrhythmia or electrophysiology team?
How frequently does the team perform AFib ablation?
What type of mapping and ablation technologies are available?
What evaluation is required before determining whether ablation is appropriate?
What follow-up will be required after returning home?
These questions can sometimes be more useful than simply choosing a hospital based on its overall reputation.
3. Post-treatment follow-up should be considered before travelling
International medical treatment does not necessarily end when a patient leaves the hospital.
AFib patients may require follow-up monitoring, medication review and ongoing cardiovascular assessment after an ablation.
International patients should therefore discuss with the treating medical team how follow-up will be managed after returning to their home country.

Atrial Fibrillation Treatment in China for International Patients
China has major cardiovascular centers offering diagnosis and interventional treatment for cardiac arrhythmias, including atrial fibrillation.
However, the appropriate hospital and specialist depend on the patient’s individual condition.
International patients considering AFib treatment in China may benefit from preparing:
Previous ECG results
Holter or other heart rhythm monitoring reports
Echocardiography reports
Relevant blood test results
Previous hospitalization records
Current medication list
Previous cardiology assessments
These records can help the receiving medical team understand the patient’s history and determine what additional evaluation may be required.

Important Medical Disclaimer
This article describes the experience of one individual patient as reported by the treating hospital.
The patient’s experience and outcome should not be interpreted as evidence that catheter ablation is appropriate for every patient with atrial fibrillation or that another patient will experience the same outcome.
Catheter ablation carries potential risks and benefits that should be discussed with a qualified cardiologist or electrophysiologist.
Decisions concerning antiarrhythmic or anticoagulant medication must be made by the patient’s treating physician. Patients should not change or discontinue prescribed medication based on information in this article.
